HELP!!!! very important!

** Mods: Please don't move this! I know that this shouldn't be in this forum but it's for an assignment and I really need feedback fast, so I thought this forum would be good. Please try to understand..

I know I should be doing this myself, and I have .. I had this huge physics assignment to do (i hate physics) and I've gotten most of the questions done, just have two questions left to do so guys, please help me out with those two questions, it's very important!

1. The human heart pumps about 60 mL of blood into the aorta during a single stroke, which lasts about 0.1 s. In a single stroke, a pulse of blood is accelerated from rest to about 50 cm/s. Calculate the average acceleration of the blood in metres per second squared.

2. An electric car accelerates from rest to 50.0 km/h in 8.20s. What is the average acceleration of the electric car in kilometres per hour per second?

I get how to do those, but i'm having trouble with the conversions =[

please help

Calculate the average acceleration of the blood in metres per second squared.-firstly, the acceleration shud be in cm/s squared. velocity, or speed are calculated in cm/s... so having an acceleration is 50cm/s, it is impossible.. but a 50 cm/s SQUARED is possible

2. An electric car accelerates from rest to 50.0 km/h in 8.20s. What is the average acceleration of the electric car in kilometres per hour per second?-

1 kilometers per hour per second = 0.277777778 m / s2

-this should help you😳
